I do have a custom recovery: the latest TWRP for FLO. I've never had touchscreen problems therein, which affirms the likelihood of a software-related issue.
I was able to reboot the tablet (I had forgotten about just holding down the power button....) - and the touchscreen is now 'back'. So there's that. Do you think that this is this the same issue as the multi-touch problems I have read so much about?
